+Disclaimer text: // High-density devices only (Maple Native)
+
+
+Board portability is implemented by adding a header file to ./libmaple with the
+name of the BOARD target, and then editing libmaple.h to add this file as an
+option.
+
+A pin maple file should be added to ./notes describing the pin numbering
+
+Files to check by hand:

+ADC Notes:
+ only using ADC1?
+ untested
+
+EXTI Notes:
+ need to update huge table in comments?
+ untested
+
+NVIC Notes:
+ I don't think NVIC_ISER3 and NVIC_ICER3 actually exist?
+ Only CANBUS and USB OTG use interrupts above #63, but I updated the nvic code anyways
+
+RCC Notes:
+ Added some clock stuff to all boards even though they aren't usable... blah.
+
+SPI Notes:
+ SPI3 is only in XL chips so didn't really handle that
+
+TIMER Notes:
+ High-density devices add an advanced timer (TIMER8) and another normal one (TIMER5).
+ TIMER6 and TIMER7 are much less useful.
+ There is some partial progress towards adding timer5/timer8 functionality,
+ but not much. This should probably all be rewritten.
+ The wirish timer implementation should be refactored to use pin numbers.
+
+USART Notes:
+ The USART/UART nomeclature is a little mixed up.
+ TODO: portability of HardwareSerial, HardwareSPI
